The world’s first HDMI 2.1 48Gbps FRL6 4×1 CEC Controlled Switch.

GUIDE-4 from ThenAudio is the world’s first HDMI 2.1 CEC-controlled switch. Early adopters find that sometimes having the latest-greatest comes at a price. The first HDMI 2.1 TVs and Projectors were often saddled with having a single HDMI 2.1-capable input. For gamers with multiple media consoles and even a dedicated gaming computer, this meant repeatedly manipulating HDMI cables to access this input. 

The GUIDE-4 provides four additional HDMI 2.1, 48 Gbps, 8K/60 fps, FRL 6 inputs that can cleverly be switched using the TV remote, though they all enter the display through the same HDMI input.

ThenAudio’s proprietary CEC interactivity visibly populates all four GUIDE-4 inputs into the TV menu, linking them through the HDMI input the GUIDE-4 output is connected to. For example, when GUIDE-4 is connected to HDMI Input 1 of a display, the onscreen data populates under Input 1 as four associated inputs. Additionally, the TV remote accesses each sub-input with the actual switching occurring automatically inside the GUIDE-4. 

More impressive, pressing a PlayStation 5 remote control menu button will issue a specific string of ThenAudio CEC commands processed by the GUIDE-4 that cues up the PlayStation to its sub-input within the TV to HDMI 1, ready for use. Essentially, a significant degree of automation occurs minus the automation system and programming woes.

With Perfect Pass-Through, the video signal never undergoes processing by the GUIDE-4, remaining bit-for-bit perfect from the source.
